The, flow o l the Water from the chainherl intofthe outlet "passage is controlled by a single 'valve which, in the form 151mm, operates in; an inclined plane to and from a'valve seat 1%, the same being in the i'orin of a ring sccured Within theoutlet opening fromthe chamber 1. The Valve for i the outlet opening comprises a central portion 15 havinga flange 16 on its lower end and a flange 17 of corresponding size at its' A'fiher ii'i'eniber 18fis secured flange 16 by a reupper end.

Theflange 17' operates Within a chamber 20 removably secured in an opening in the up? per ivaH or the chamber '1. I I

The outlet alvethus eonstrueted is slid- "ahl'e upon a'1-od21 extending throughan appropriate mounting 22- at the lower side of thechainber 1 and having its upper end operating'" Within a guide 23, constituting a partof the meinlier supporting the guide 20.

,From the orego'inggit wlll lie-apparent impeded by the were; r ssur in the chain- Y valve operates, because said valve ,balan' in both directions, that .isagainst the flange 16 at the lower endof the valve and the fiangel? at the upper endof the-valve. It is also apparent that the inlet valve will be closed when released bythe locking mechanism, justas rapidlyas water asses through the vent 17 to fill the space a ove' the valve when thefsame moves ,toward closed position, and that the rapidity of saidmovement of the valve isrinproportion to the ..size of the vent permitting such passage of the water For regulating the flow of the water through the vent passagel'? an adjustable screw 17 is provided, the same be- .ing supported by an appropriate bracket or support in connection with'the valve. .The screw is ad ustabletoward and away from .the vent opening so that therapi'dity with which the water may enter the space above the valve maybecontrolled and'varied as desired.

V .Theoutlet valve ise quippedwith mechainto the receptaclefor receiving the same. In. the embodiment illustrated the mechanism for releasing .or-unlocking the outlet valve is under control of a float device.

As shown a-support for? the operating and locking mechanism for theoutlet valve is secured to the lower wall: ofthe chamber in' which the valve is mounted. A lever 31 is mountedonapivot 32in said support,

preferably below herod 21. The lever 31 i carries a roller33 adj acentto the end of the rod-31 so that when saidlever is raised the V roller will operate against the end of the rod and raise the-rod, thereby opening the outlet valve. The roller makes the operationof thevalve'stem freeand easy, since the roller can turn upon. its pivot andthereby accommodate itself to themov'em'ent of the parts. A leve'r 34 mountedfona pivot 35' has oneend connected with a link 36and its opposite end connected with a link '37. The link- 36 is also \pivot'ally-connected with an arm 38 rigidwith the lever=31, said parts occupying positions approximately as illus-- trated in-Fig. l when theoutlet valve is closed. \Vhen the lever 31' is raised as required to open the o'utlet valve, the pivots connecting'the link 36 with the level- 34 and with the arm'38 are on "a straight line parallel with the-axis of-the rod 21, as a result ofwhichrthe lever 31 will be locked in its raised position, thereby retaining the outlet vaflve open. In order to permit the.- lever- 31- tereturn I to itslower pos i-tion, as shown, and; thereby enable'the outletvalve to close, it'ais ne es ary toi-break the toggle look, by

by gravity to closed position. valves also may be held in then-closed posioperating the lever 34 eiiectively to move the pivotal connection between the same and the link 36 out of alinement with the pivot 35 and the pivot connecting the link 36 withthe arm 38. When the toggle lock is-thus broken the'power of the spring 26 presses the outlet valve to closed position.

At this oint it is appropriate to, advert sure of thelwater when the outlet valve is open.j However, when the outlet valve is closed the-chamberl; becomes filled with water on both the influent and eifluent sides of the inlet valves. Thus the pressure against both sides of the inlet valves becomes balanced when the outlet valve is closed, so that said inletyalves are permitted to be moved The inlet tion by proper adjustment of the members 9, and when the inlet valves are retained in closed position the chamber in which the outlet valve is mounted may be opened to afford access to the interior of the entire chamber inorder to, enable any oiv the parts to be removedorreplaced or repaired. 4

Downward movement of the lever 31 is limited by an adjustable abutment 39 which is in the form of a screw carried by an arm on the support 30;. and upward movementv of said'lever is limited by a similar abutment 40 which is. also carried by an arm of the support 30.] Extent of movement of the lever 34; and the link 36i toward locking position is limited by an adjustable abutment 4:1 which, preferably, is in the form of a screw adjustable in the support 30. The provision of the adjustable abutments 39 and 40 to limit. inovementof the lever 31 prevents any 1 again .to e inlet valves which, as previ v ously described, are held open by the presundue strain being exertefd'upon any of the parts-connectedwith. the lever by careless or unnecessarily forcible operation, as would otherwise occur. I

A lever 42' is. pivotally supported at .43 and hasone end connected with thelink 37 and the opposite end supporting a bar 44.

A float'515 is within a chamber 16 whichis l 1 arrangedto receive water from the outlet pipe 13, .orthe receptacl'eiinto which the water is'discharged in a well understood manner.-- Af rod 47 is connected with the float andv is adjustably .securedto thebar 4 1 by a retaining device comprising and a detent49. 1 1 1 I pFrom the foregoing description of the connection between the float and the locking devices of theroutlet valve, it is ap'parent that when theweight-of the float-is support- "ed from .the-leve1f42 and the connections therefrom'to the lever 31 the toggle lock, comprising the lever 34-- andthe link '36, will be moved certainly to locking positionwhen the lever 31 is; raised. fThis "result is attained because the 'weightgofthe float. actu a bracket 48 when the outlet valveswas open.

ates the lever 34 in a direction to movethe pivot connecting the samewith the link 36 to locking position toward the abutment 41. This result is attained ithout the use of springs or other actuating devices usually employed for this purpose. Also, when the water in the chamber 46 rises sutliciently t0.

waterrequired toactuate the float and unlock the outlet valve may bevaried at will. Thus by connecting the rod 27 in a lower position upon the bar' 44' and thereby lowering the'float in the 'chamber 46,- a comparatively small quantity of'water will raise the float and unlock the outlet valve whereas by connecting the rod' 47' to the bar 44 in any higherposition a greater quantity of water may pass the outlet valve before the float will be raised and the outlet valve unlocked. -And this variation may be eflected withinany desired limits.

The connecting device 48-'49 which is conventionally illustrated in Fig. 1 is convenientlyoperable so that this adjustment of the float in any of the selected positions may. be made quickly and without the use of any special appliances or tools for that purpose.

Also,- it will be observed that when the float is actuated upwardly by the water to unlock the locking mechanism of the out let valve, the float is raised out of the water by the movement of the parts under the impulse of the valve rod 21 actuated by r the spring 26 which closes the outlet valve.

The raising of the float out'of the'water dispenses with the vibration of the float and the other parts in connection therewith from the surging of thewater in the tub or'reoeptaole into which the Water is delivered,

so that irrespective of the disturbance of the water, the valve mechanism remains stationary and undisturbed. 7
